If you've registered these in the past day or so, you can ask the registrar you gave your money to for these trademarked names, for a refund, either send them an email, contact us page or call them on the phone. You can usually delete names within the first 5 days. A credit should then be applied to your account. Before you rush out to buy more, read as much as you can on this forum first, DNJournal.com and NameNewbies.com
This will stand you in better stead for the future. Reading and researching is key here in this industry until such time you can make snap decisions that work in your favour.
Remember too when developing websites, how much time you put into web development. Sometimes you can be flogging a dead horse, other times with the proper research done in advance, you can half your time put in and get twice the return on investment when you come to sell your domains. This will enable you like a springboard platform, to be that much more effective with your plan of action for the future.
Reading and research is the key point in this industry.
Best of luck.
